CHARLES MOSER ZIMMERMAN, OF CINCINNATI, OHIO.

GLUE-MELTING APPARATUS.

Application filed December 7, 1909.

To all whom tt may concern:

Be it known that I, CHARLES M. ZIMMER- MAN, a citizen of the UnitedStates, and a resident of Cincinnati, lin the county of Hamilton andState of Ohio, have invented a new and Improved GlueMelting Apparatus,of which the following is a full, clear, and exact description.

The invention is an improved apparatus for the melting of glue, andbelongs to the general type of such appliances as disclosed inapplications filed by me October 29, 1908, and October 29, 1909, SerialNumbers 460,144 and 525,351, respectively, said appliances embodying asteam vessel in which is located a glue converter and a glue collector,the converter having a perforated or reticulated bottom through whichthe glue is discharged to the collector beneath.

The present invention has for its purpose to collect and heat water inthe lower portion of the steam vessel for use in keeping small glue potshot, to maintain a predetermined water level without the loss of steam,to prevent water from the steam pipe being blown into the collector orwater of condensation running into the collector from the sides of theconverter, and to provide for the passage of chilled glue from the gluepots into the apparatus and its reheating before dropping into theconverter.

Reference is to be had to the accompanying drawing, wherein is shown incentral vertical section a gluemelting apparatus embodying my invention.

The apparatus comprises a steam vessel 5, a collector 6, a converter ormelting vessel 7 a cover 8 and an upwardly and inwardly inclined wall 9secured to and forming in connection with the upper portion of thevessel, a gutter, and on which the converter removably seats; all ofwhich are features of the apparatus disclosed in my applications lastreferred to.

The steam vessel of the present apparatus is made sufciently long toprovide for the collection and heating of water in the lower portion foruse in the outer jackets of small glue pots to keep the glue in thelatter from readily chilling. The water level is maintained somedistance below the top of the glue collector 6, generally at or aboutthe level of the funnel bottom portion of this part of the appliance, byan overflow pipe 11 and a filling pipe or funnel 12, each communicatingwith the vessel at points closely Specification of Letters Patent.

Serial No. 531,862.

adjacent and connecting with a pipe 13, the latter extending asubstantial distance below the water level, generally terminating ashort distance above the bottom of the steam vessel, thus permitting ofthe escape of the water from the steam vessel, when the water levelrises above the inlet, to the overow pipe, or the introduction of waterinto the steam vessel, should additional water be required, without theescape of the steam at these points.

A pipe 14 from a suitable source of supply has a trap 15 adjacent to thevessel and passes within the vessel near the bottom and terminates in avertical portion a substantial distance above the water level, the upperend of the pipe being closed and having perforations 16 a short distancetherebelow for the distribution of steam in the steam vessel to bothsides, the perforations being arranged intermediate the water level andtop of the glue collector, so that the water of condensation in the pipewill not be blown into the collector, nor will the water within thesteam vessel pass into the steam pipe through the perforations.

The side walls of the glue converter or melting vessel are arrangedoutwardly from the open upper end of the collector, so that the waterrunning down the converter by reason of the condensed steam will notpass into the collector, the perforations in the bottom of the converterbeing confined to the space directly over the collector, as shown, sothat all of the glue as it melts will pass into the collector, thecollector discharging through the side of the steam vessel adjacent tothe bottom. The hot water in the steam vessel when needed for thejackets of the glue pots is drawn off through a faucet 18, shown indotted outline to be arranged at the side of and near the bottom of thesteam vessel.

The cover 8 is preferably of conical form so that the water of thecondensed steam will flow down the sides into the gutter, from which thewater is led olf to a point below the collector by a pipe 19. The cover8 at its apex has a tubular extension 20 for the insertion of a funnel21, and below said extension has a conical hood or member 22 pointingupwardly and shedding into a larger conical member or funnel 23reversely arranged and discharging over the converter, the members 22and 23 affording a large heating surface and serving to readily reheatthe chilled glue when the latter is poured from the glue pots into thefunnel 2l.

In operation, the glue to be melted is placed within the converter 7 andthe latter seated in the steam vessel, when the cover is applied and thesteam turned on. The steam pipe passing through the water in the lowerportion of the steam vessel keeps the waterv sufficiently hot for thepurpose intended, the water being constantly added to by thecondensation of the steam, which, if insuicient to keep the waterl levelup to the overflow pipe, is added to through the inlet pipe or funnel.The glue as it melts passes into the collector, from which it flows tothe outside of the vessel.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

l. The combination of a steam vessel, a glue collector arranged withinthe vessel and discharging to the outside thereof, a glue converterarranged within the vessel over the top of the collector and dischargingthereinto, and means to maintain a head of water in the lower portion ofthe vessel, with the normal level thereof located below the top of thecollector.

2. The combination of a vessel, a glue collector arranged within thevessel, a glue converter arranged within the vessel over the collectorand discharging thereinto, means to maintain a head of water within thelower portion of the vessel, and a steam pipe passing into the vesselbelow the normal water level and discharging at a point intermediatesaid level and the top of the collector.

3. The combination of a vessel, a glue collector arranged within thevessel, a glue converter arranged within the vessel over the collectorand discharging thereinto, and a steam pipe passing into the lowerportion of the vessel and terminating in a vertical portion, with theupper end thereof closed and having a discharge perforation arranged inthe side below the top of the collector.

4. The combination of a steam vessel, a glue collector arranged withinthe vessel, a glue converter arranged within the vessel above thecollector and discharging therein, a water overliow pipe leading fromthe vessel at a point a substantial distance above the bottom thereofand below the top of the collector, and means covering the inlet of theoverow pipe, extending a substantial distance below the normal waterlevel and open at the lower portion thereof.

5. The combination of a steam vessel, a glue collector arranged withinthe vessel, a glue converter arranged within the vessel over thecollector, means to maintain a head of water in the lower portion ofthevessel, an inlet pipe discharging into the vessel near the normalwater level, and a cover closing the inlet end of the pipe, extending asubstantial distance below the water level and open at the lower portionthereof.

6. The combination of a steam vessel, 'a glue collector arranged in t-hevessel and open at the top, and a glue converterarranged over thecollector and having a perforated bottom arranged to discharge into thecollector, with the sides of the converter arranged outwardly from theopen upper end of the collector.

7. The combination of a steam vessel, a glue converter arranged withinthe vessel, a cover for the vessel, heating members discharging into theconverter and arranged under the cover, and means for introducing gluethrough the cover over the heating members.

8. The combination of a steam vessel, a glue converter arranged withinthe vessel, a cover for the vessel, a funnel carried by the cover at theinner side thereof and discharging into the converter, a conical heatingmember shedding into the funnel, and means to introduce glue through thecover o-ver said member.

9. The combination of a steam vessel, a perforated glue converterremovably arranged in the upper portion of the vessel and substantiallycutting off the passage of the steam thereabove except through theperforations thereof, and a glue collector arranged under the converterwithin and surrounded by the vessel and discharging to the outsidethereof. l

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
